摘　　要：采用湿法拉膜成型工艺,以收缩率大的(Zn_(0.7)Mg_(0.3))TiO_3(简称ZMT3)材料作为夹层材料,以收缩率相对小的铁氧体材料(Ni_(0.8)Zn_(0.12)Cu_(0.12))Fe_(1.96)O_4(简称NZC)作为两边收缩控制层,获得"三明治"叠层结构.以独特的零收缩差技术,制备了界面结合紧密,无翘曲变形、开裂等缺陷,可于900℃烧结的"三明治"结构叠层共烧体,其最佳介电性能为:ε_r=12,tanδ=9.84×10^(-4).这项新技术的提出,为解决异种材料共烧时所经常产生的翘曲、变形等缺陷提供了一种新的解决思路.A novel zero-shrinkage-difference technique was introduced to eliminate the camber or cracks in cofired composites without the degradation,A sandwich structure of（Zn（0.7）Mg（0.3））TiO3（ZMT3） dielectric/（Ni（0.8）Zn（0.12）Cu（0.12））Fe（1.96）O4（NZC）ferrite multilayer composite was designed and prepared by using tape-casted technique,with ZMT3 as interlayer,and NZC as top and bottom layers.The produced sandwich structure shows no camber and cracks after being co-sintered.The cofired samples exhibit good dielectric performance（εr=12,tanδ=9.84×10（-4））,and low firing characteristics（900℃）.Due to their dielectric performance,low firing characteristics,and realizable co-firing compatibility,the sandwich structure of ZMT3 dielectric/NZC ferrite multilayer composite can serve as the promising medium materials in the multilayer LC filter.
